摘　　要：目的 :观察小儿过敏性紫癜时脑血管血流及血管阻力变化。方法 :对 32例过敏性紫癜患儿于入院 2 4 h内进行脑彩超检测 ,分别探测基底动脉 (BA)、双侧椎基动脉 (VA)、双侧大脑前动脉 (ACA )、大脑中动脉 (MCA)、大脑后动脉(PCA) ,并选用收缩期峰流速 (Vs)、阻力指数 (RI)为观察指标。同时进行脑电图单双极描记及过度换气和睁闭眼试验。结果 :脑彩超 2 9例 (90 .6 % )表现为单、多条血管血流速度加快 ,2 5例阻力指数增高。脑电图非特异性异常 7例 ,癫痫样放电 1例。结论 :患过敏性紫癜时脑部血管也同时受累并出现血流动力学变化。Objective:To investigate the changes of cerebral blood flow and resistant.Methods:32 cases with hypersensitive purpura were investigated.The blood flow of basilaris artery,middle cerebral artery,posterior cerebral artery and the resistant index were detected by cerebral color ultrasonograph.The cerebral wave was also recorded by electroencephalogram (EEG) within 24h after hospitalization.Results:29 cases showed the speed of blood flow and 25 cases showed the high resistant index.Seven cases showed abnormal EEG and the epilepsy wave was found in one case.Conclusion:There is cerebrovascalar lesion in patients with hypersensitive purpura and results in the change of blood flow.Cerebral color ultrasonograph can detect this change accurately.
